NullPointer Exception In running testCases via Selenium webDriver in Chrome - selenium

Question

I am trying to run my test cases on Chrome and I had copied the path in the Properties file,but still console is throwing annoying statements like:
ERROR: The path to the chromedriver executable must be set by the webdriver.chrome.driver system property; for more information, see http://code.google.com/p/selenium/wiki/ChromeDriver. The latest version can be downloaded from http://code.google.com/p/chromium/downloads/list
FAILED CONFIGURATION: #BeforeTest startWebSession
java.lang.NullPointerException

Answer 1

One thing I have found is that the Chrome driver cannot be started from within Eclipse. It must be run from a command prompt. At least on Windows 7 64-bit.
Trying to run it from within Eclipse produces this exception:
Exception in thread "main" java.lang.IllegalStateException: The webdriver.chrome.driver system property defined chromedriver executable does not exist: C:\Windows\System32\chromedriver.exe
This problem only occurs for Chrome. IE and FireFox work fine from within Eclipse.

Answer 2

Download the chrome driver from http://code.google.com/p/chromedriver/downloads/list
Initialize your driver object in the following manner -
System.setProperty("webdriver.chrome.driver","C:\\chromedriver.exe");
WebDriver driver = new ChromeDriver();
By doing this the chrome driver works properly.

Answer 3

This is how do I initialize the ChromeDriver:
public RegulationUI() throws Exception{
ChromeDriverService service = ChromeDriverService.createDefaultService();
File file = new File(RegulationUI.class.getResource("/chromedriver.exe").toURI());
System.setProperty(ChromeDriverService.CHROME_DRIVER_EXE_PROPERTY, file.getAbsolutePath());
ChromeOptions options = new ChromeOptions();
options.addArguments("--start-maximized");
driver = new ChromeDriver(service,options);
}
BTW my test class is named RegulationUI
Try this, it works for me and moreover, I know that this is "multicomputer" solution - our project is in subversion and this way everybody can run it, even if we have differently setup where exactly on disk the "working folder" for IDE is

Answer 4

Please download chromedriver.exe for Google chrome browser
please download IEdriver.exe for Internet explore.
Please And kept these files in a root folder of windows for simplicity. Lets consider your operating systems installed on c:\ (C Driver) create a folder name Selenium on C-Drive and Kept these binary(.exe) files. like c:\selenium
in your Testcase/testScript Write as
//For Chrome Browser:
Webdriver driver = new ChromeDriver();
java.io.File file = new File("c:\\selenium\\chromedriver.exe");
System.setProperty("webdriver.chrome.driver", file.getAbsolutePath());

If you are using maven then try to use following in your pom:
<dependency>
<groupId>io.github.bonigarcia</groupId>
<artifactId>webdrivermanager</artifactId>
<version>RELEASE</version>
</dependency>
and use it like this for chrome in your setup:
ChromeDriverManager.getInstance().setup();
driver = new ChromeDriver();
